Application filed August 8, 1919. Serial No. 316,235.

To all whom it may concem:

Be it known that we, LESTER P. WINoH ENBAUGH and Lawrence GENTILE,citizens of the United States, residing, respectively,

at Hyde Park and Melrose, in the counties of Suffolk and Middlesex andState of Massachusetts, have invented certain new and usefulImprovements in the Processes of Applying Coloring Liquid to Paper; andwe do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertainsto make and use the same.

This invention relates to a process ofap plying dye, stain or othercoloring liquid to paper or similar material.

The primary object of the invention is to produce a process for use inapplying coloring liquid to paper by which novel designs and artisticeffects may be produced in an eflicient and reliable manner. 1

With the above object in view the invention consists in a processinvolving certain novel features hereinafter described and particularlypointed out in the claims.

In the drawing the figure is a view in side. elevation of an apparatuswhich may be employed in carrying out certain steps in the presentprocess.-

In the present process a coloring liquid is employed which in practicehas been made by dissolving a dye in a liquid solvent. The dyesubstances which are used should be such that they are completelysoluble in the liquid solvent, leaving no sediment. Preferably coal taror aniline dyes are employed, such dyes having in addition to theirready solubility the property of transparency which enables almostcountless variations in color and designs tobe produced by the posedrelation at certain points. It has been found particularlyadvantageous'to employ as solvents for the dye alcohol, gasoline orsimilar organic solvents since such solvents produce a rapidly dryingsolution and cause the coloring liquid 'to penetrate the paper to aconsiderable degree, thereby increasing the artistic effect of thedesign.

After the dye is completely dissolved. in the liquid solvent thecoloring liquid is introduced into a suitable container from which itmay be drawn for transfer to the paper.

and the paper sothat the fabric .receptable in just there is never anyexcess of liquid at application ,of the colors in super- To withdraw thecoloring liquid from the container in the regulated quantity requiredfor transfer to the paper a section of sheet fabric is introduced intothe liquid in the container and is arranged with one end projecting fromthe liquid. This section of sheet fabric must be made of such materialand must be so constructed that the coloring liquid will be drawn fromthe container through the same by capillary action. Certain kinds-ofwoven wool felt have been found to be well adapted for this purpose.

The coloring liquid may be transferred from the fabric to the paper byplacing the paper in-contact'with the end of the fabric,"

which projects from the color containing' receptacle and relativelymoving the fabric is carried along the surface of the paper. Thecoloring liquid will thus be Withdrawn from the the amount required forthe paper, the liquid being the fabric to the end thereof application todrawn through which engages the paper as fast as it is applied to thepaper. The quantity of liquid withdrawn is regulated by" the fabric sothe point of application to form blots or other imperfections in thedesigns.

The coloring liquid may .be ap lied to the paper in stripes or streaksby notching the edge of the fabric which engagesthe paper. Two or morecolors may be applied to the paper at the same time by the use of two ormore sections of fabric each dipping into a separate receptacle andengaging the surfaceof the paper at different points. When two or moretransparent colors such as are formed by the use of solutions oftransparent dyes are applied so that at certain points the colorsoverlap or are superposed, variations in the resultant colors from thecolors applied are produced giving highly artistic effects.

The amount of color paper may be regulated by the use of fabrics ofdifferent thicknesses, the greater the thickness of the fabric the morerapid the flow of the liquid therethrough. Also the amount of the liquiddeposited on the paper may be varied by varying-the rapidity of therelative movement of the fabric and the discharged upon the;

paper. The greater the speed with which surface of the roll.

the paper is passed, along the'edge of the fabric the less will be theamount of the coloring liquid deposited on the paper. The distributionof the coloring liquid will also vary with variations in theconstruction of the fabric employed llnstead of engag the paper directlywith the fabricto transfer the coloring liquid from the fabric to thepaper, the fabric may be engaged with a roll or other color receivingdevice intermediate the fabric and the paper and carried by this devicefrom the fabric to the paper. The figure of the drawing illustrates anapparatus which may be advantageously employed in transferring theliquid from the fabric to the'paper in this way. In the illustratedconstruction the coloring liquid is contained in a receptacle 2 and asection of sheet fabric indicated at t is located with one endthereofdipping into the liquid in the receptacle and with the other endthereof resting on a roll indicated at 6 and is held in contacttherewith by a weight 8. Below the roll 8 is a cooperating roll 10between which and the roll 6 the paper is passed as clearly shown in thedrawing. lln the operation the rolls are rotated in the directionsindicated by the arrows.

The surface of the roll 6 is formed with elevations and depressionshaving any suitable fo and arrangementto draw the liquid as requiredfrom the fabric, and the fabric d thus contacts with and deposits thecoloring liquid upon the high points on the then transferred by the roll6 to the paper as it passes between the rolls in a design correspondingwith the design formed on the surface of the roll 6. The roll 10 mayhave a smoothperiphery if desired. lln the illustrated construction,however the surface of the roll 10 is also provided with elevations anddepressions corresponding with those on the roll 6 so that the paper isembossed in passing between the rolls.

The mechanism above described is illustrated, described and claimedinapplicants copending application Serial No. 316,233., filed on the samedate as the present application. Tn an application Serial No. 316,-234:, also filed on the same date, applicants have illustrated anddescribed a process related in certain aspects to the present process.

Having explained the nature and object of the invention, and havingspecifically described the manner in which it may be applied what isclaimed is: J

l. The process ofmaking colored paper which comprises withdrawing asolution of a dye in alcohol or asimilar solvent from a supply inregulated quantity through a capillary. sheet fabric and progressivelytransferring the regulated quantity of the The coloring liquid is Irate-pea solution thus withdrawn to a moving sheet of paper.

2.; The process of making colored paper which comprises withdrawing asolution of a dye in alcohol or a similar solvent from a supply inregulated quantity through a sheet of capillar fabric, progressivelytransferring the so ution from the fabric to a moving colorreceivingdevice and applying the solution transferred to said receivingdevice to the paper by passing the paper past said receiving device incontact therewith.

3. The process of making colored paper which comprises withdrawing asolution of a dye in alcohol or a similar solvent from a supply inregulated quantity through a section of capillary sheet fabric,transferring the solution from the fabric as it is withdrawn from thesupply to a rotating color receiving roll and applying the solution tothe paper by passing the paper along the roll in the direction ofmovement of the roll and incontact therewith.
